• COJALI is an European company that manufactures products and diagnosis for commercial vehicles.

    COJALI, with more than 20 years of experience in the manufacture of spare parts for commercial vehicles, began with the production of viscous fan clutches, plastic blades, valves, servo clutches, etc. Then, there were just a few references being manufactured, however, the research was already becoming one of the most important pillars of the company. Year after year, this fast process is bearing excellent fruit, strengthening COJALI and JALTEST as reference brands in Europe, USA and the rest of the world.
